        First, I take it 'brayton cycle' means gas turbine.

        I don't know about *that*, but a few years ago there was an article
in the newspaper (I presume it was that Miami Herald- I didn't save the
article, so I'm guessing).  The article referred to the possibility of third-
world (or other) powers in the post-cold war era using low-tech diesel
subs for terrorism or similar activities.  One type of technology was a
diesel sub who's interior hull was 'wrapped' with large holllow continuous
tubing.  Simply, one end of the tubing was connected to the intake of
the diesel, and the other end was connected to the exhaust.  This would
create a kind-of 'portable' air supply for the diesel engine to run off while
submerged for maybe 24 (or more?) hours.  Low-tech, and practical.
